Though it has a unique grille and headlights, the Aqua Cross concept shares its other basic design cues with the Toyota Aqua Air concept – a convertible version of the Prius C that is also headed for the Tokyo show.

Like the Aqua Air concept, the Aqua Cross is said to be powered by the regular Prius C’s hybrid powertrain, teaming a 54kW/111Nm 1.5-litre Atkinson-cycle petrol engine with an electric motor for a total system output of 74kW.

Full details of the Toyota Aqua concepts will be revealed when the show kicks off on November 20.
